Chacko, you could perform an SNMP walk against the switch to get an idea of the OIDs and their description. Though I do not think we have one for duplicate IPs.
Please be aware that you can detect Duplicate IPs based on a test that would inform if two device respond to an ICMP request. Please read the following article for more detail:

In turn, if you have an SNMP manager / NMS, such as the marvelous NetSight, you then could create an alarm based on the EMS generated in the show log output via syslog.
